The IWOTE’14 took place for the 4th time in Bremen on April, 09-10. BIAS – Bremen Institute of Applied Beam Technology was the host of this internationally staffed workshop, which provided the opportunity for specialists from industry and science to make contact with each other and to discuss recent scientific and technological results and ideas. Chairman Professor Dr. Frank Vollertsen – CEO of BIAS – welcomed presenting and participating experts from ten countries even from Australia and South Korea.

The workshop was intended to promote the exchange of experience at international level and foster the dialogue between science and industry, related to the shape changing phenomena in thermal forming and welding.

Prof Na from Korea talked about CFD-Simulation of Welding Process and its Application to Prediction of Welding Distorsion

Welding distortion is a major cost factor in production for industry. For example, two million EURO are accounted for straightening works for a middle class cruise vessel.

Hence, it is an important economic interest to control welding distortion and therefore this topic was the main topic of IWOTE’14.

Two days with 22 expert presentation e.g. by Professor Suck Joo Na (Korea) and Professor Naoki Osawa (Japan), and encouraged discussions gave more than an overview to the state of research. Besides from presentations dealing with the rather classical IWOTE topics thermal forming and welding distortion with its countermeasures, an upcoming topic was the simulation of additive manufacturing techniques like Selective Laser Melting (SLM).

The next IWOTE will be in 2017, also taking place in Bremen.

Information“Knowledge for application” – with this mission BIAS - Bremer Institut für angewandte Strahltechnik (Institute for Applied Beam Technology) is a reliable partner for research and development in the field of laser applications. The two divisions “Material Processing and Processing Systems” and “Optical Metrology and Optoelectronic Systems” allow the institute to develop new laser based technologies and solutions.

Furthermore, the competence center “Centr-Al” provides unique expertise concerning welding of aluminum and other modern lightweight materials. The developments of BIAS find their way into aviation and aerospace, shipbuilding, railway and automotive industries as well as into design and production of semiconductor and optoelectronic devices and measurement and testing technology.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
